Time and Mass Measurement Conversion Calculator
Similitude is the theory and art of predicting prototype performance from
model observations done with the help of a measurement conversion calculator
online. Whenever it is necessary to perform tests on a model to obtain mass or
time measurement conversion information that cannot be obtained by analytical
means alone, the rules of similitude must be applied. The mass measurement
conversion theory of similitude involves the application of π-groups, such as the
Reynolds number or the Froude number, to predict time measurement
conversion prototype performance from model tests. The art of similitude enters
the problem when the engineer must make measurement conversion decisions
about model design through a calculator before the model construction,
performance of tests, or analysis of results that are not included in the basic
theory.
Present engineering practice makes use of mass and time measurement
conversion model tests more frequently than most people realize. For example,
whenever a new airplane is being designed, tests are made not only on the
general scale model of the prototype airplane but also on various calculator
components of the plane. Numerous tests are made on individual wing sections
as well as on the engine pods and tail sections.
Models of automobiles and high-speed trains are also tested in wind tunnels to
predict the measurement conversion drag and flow patterns for the mass
calculator prototype. Information derived from these model studies often
indicates potential conversion calculator problems that can be corrected before
the prototype is built, thereby saving considerable time and expense in
development of the prototype.
